Value Collection 01188515 No. 51 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188515 is a wire gauge jobber-length drill bit sized to No. 51 (0.0670 inches) with a 118-degree standard point angle. Manufactured from high speed steel (HSS) with an oxide coating, this bit is built for general-purpose drilling in steel and cast iron. The straight cylindrical shank seats securely in standard drill chucks. Two regular spiral flutes run the length of the 1-inch flute zone, evacuating chips efficiently during through-hole and blind-hole operations. Overall length is 2 inches, keeping the bit compact and rigid for tight-tolerance work in light fabrication, maintenance, and mechanical assembly applications.

This bit is suited for trade and industrial use where wire gauge hole sizing is required. No. 51 wire gauge bits are commonly used in metalworking operations including tapping pre-drill, clearance holes, and precision hole work in ferrous materials such as mild steel and cast iron. The web-thinned, tapered-web design reduces thrust force at the point, making hand-fed drilling more manageable. Right-hand cutting direction is standard for use with conventional drill presses, hand drills, and magnetic-base drills.

Key Features

• No. 51 wire gauge size — 0.0670-inch decimal diameter for precision hole sizing
• 118-degree standard point angle with web-thinned, tapered-web geometry for reduced entry thrust
• High speed steel construction handles steel and cast iron without specialized tooling
• Oxide coating provides light corrosion resistance and reduced friction at the cutting edge
• Regular spiral flute pattern promotes consistent chip evacuation in through and blind holes
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose replacement or stock drill bit for use in standard drill presses, hand drills, and magnetic-base drills accepting straight-shank bits. Intended for drilling steel and cast iron workpieces in light fabrication, maintenance, and mechanical assembly environments.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and mechanical trade professionals. Secure the straight shank fully into a keyed or keyless chuck before operation and verify concentricity before drilling. Always wear eye protection and ensure the workpiece is clamped or fixtured before applying feed pressure. For tapping applications, confirm the pre-drill diameter matches the tap manufacturer's specification before proceeding.
